Method for the control of an assembly
First Claim
1. A method for the control of an assembly by a control unit, in particular in a motor vehicle, wherein the assembly includes at least one component, at least one actuator associated with the component and an additional control unit having a first non-volatile memory section which is connected to the control unit, with the control unit including a second non-volatile memory section, comprising:
- reading out and transmitting classification information associated with the assembly and stored in the first non-volatile memory section to the control unit, the control unit being distinct and spatially separated from the assembly;
storing the transmitted classification information in the second non-volatile memory section of the control unit; and
reading out and transmitting the classification information stored in the second non-volatile memory section to the additional control unit, wherein the classification information transmitted to the additional control unit is stored in the first non-volatile memory section if the first non-volatile memory section does not contain any classification information and the classification information transmitted to the additional control unit is not stored in the first non-volatile memory section if the first non-volatile memory section already contains classification information.

Abstract
A method for the control of an assembly by a control unit, in particular in a motor vehicle, wherein the assembly includes at least one component, at least one actuator associated with the component, and an additional control unit having a first non-volatile memory section that is connected to the control unit. The control unit includes a second non-volatile memory section. Classification information associated with the assembly and stored in the first non-volatile memory section is read out and transmitted to the control unit. The transmitted classification information is stored in the second non-volatile memory section. Subsequently, the classification information stored in the second, non-volatile memory section is read out and transmitted to the additional control unit. The disclosure furthermore relates to an assembly group that comprises the assembly and the control unit, with the control unit and the additional control unit of the assembly being connected to one another by a data transmission path.

16. An assembly group having a controllable assembly and a control unit, in particular for a motor vehicle, the controllable assembly comprising:
-
at least one component; at least one actuator associated with the component; and an additional control unit having a first non-volatile memory section, with the control unit including a second non-volatile memory section such that the control unit and the additional control unit are spatially separated and connected to one another by a data transmission path, wherein the first non-volatile memory section stores classification information associated with the controllable assembly; the data transmission path is made such that the classification information is transmitted from the additional control unit to the control unit; and the control unit transmits the classification information to the additional control unit, wherein the additional control unit includes a test unit that checks the memory content of the first non-volatile memory section and stores the classification information, or parts thereof, transmitted to the additional control unit in the first non-volatile memory section only if no classification information is stored in the first non-volatile memory section. - View Dependent Claims (17, 18, 19, 20, 21)

22. A method for controlling the transfer of drive torque in a motor vehicle from a drive unit to an axle assembly, comprising:
-
providing a torque transfer unit having a first rotary member driven by the drive unit, a second rotary member driving the axle assembly, a friction clutch disposed between the first and second rotary members, an actuator for controlling engagement of the friction clutch, and an actuator control unit operable to control actuation of the actuator in response to a control signal; providing a vehicle control unit operable to receive information on the operating state of the vehicle and provide the control signal to the actuator control unit, wherein the actuator control unit is spatially separated from the vehicle control unit; storing classification information associated with at least one of the friction clutch and the actuator in a first memory section of the actuator control unit; transmitting the classification information from the first memory section for storage in a second memory section of the vehicle control unit; and transmitting the classification information stored in the second memory section to the actuator control unit, wherein the classification information transmitted to the actuator control unit is stored in the first memory section only if the first memory section does not contain any classification information and the classification information transmitted to the actuator control unit is not stored in the first memory section if the first memory section already contains classification information. - View Dependent Claims (23, 24, 25)
